To all whom it may concern:

Be it known that l, ALMOND ll. Summen, a-citiaen oi the/United States, and a resident of Lancaster, in and State of New York, have invented a new and useful improvement in Storage-Battery Cells oli which the following is a specification.

My invention relates to storage battery cells and more particularly to the sealing and unsealinpg of the covers of' the battery jars.

"l-'he objects of the invention are to provide means 'for sealing covers on the 'jars and means for unsettling the covers an for repairing leaks in the sealing compound` and the invention consists in ellicient and durable means for readily attaining these objects.

lFurther 'features and advantages of the invention will more fully appear from the following inscriptiontaken in connection with the accompanying" drawings formingT a ot this specification, and in whichFF lfinue l is a side elevation ot' a storage battery cell, partly in section` provided with the preferred embodiment ol my invention; Fig. 2 is a` top plan view ot' said cell; and Fiend' shows a detail.

Referring to the drawings` 1 represents a hard rubberbattery jar provided at its sides with glass plates 2 'lor supporting the positive and negative battery plates 3 and 4. The plates are each Tu'ovided with upwardly extending lugs i and 6, the lugs 5 and 6 being;` lead `burned to positive and negative bus bars 7 7, respectively. Between the positive and negative plates 3 and :l are placed suitably suim'orted separutin1 strips S. The cell jar is closed by a cover 9 and the positive and negative plates 3 and 4: are held spaced apart at the points where tiey are.supported by the glass plate 2 by rubber se'iaratinp; strips The center of the cover is provided with a suitable ventilatingr outlet duct 1l and the cover is also provided .with two ventilatinf: inl-et ducts 12 located near the ends ot' the cell. From each ot the negati ve and positive bus bars Z 7 there extends a terminal 13. Each terminal extends up through the cover 5l and is provided with some suitable terminal connection 'piece il, the terminal and 'the connection piece in the particular illustration shown being protected by :i suitable nonthe county of Erie" corrodible casing l5 which, present invention is concerned, may be considered as a partof the terminal itself.

rlShe cover 9 at its outer edge has a groove 1G formed therein extendingr around the cover, in which is placed a strip 17 of suitable material, preferably some soft or {lexible material as, for example, soft rubber,

which is adapted to fit against the shoulder of the groove so as to be pressed tightly against the inner wall of the jar to prevent leakage between the cover and the inner wall ot the jar, ot' a sealing' compound 18 which, in the embodiment of the invention shown, is confined above this strip in a trough formed by the inner wall of the jar, the edgeof the cover and a vertically pro- 'jecting flange or ridge 19 projecting up'irom the top surface ot the jar. The compound may be any bituminous or asphaltum fcompound. The ridge i9 not only serves -the purpose of holding the i while hot so that it may be readily and economically applied and pressed firmly down between the inner wall of the im" and the cover by simply pressing upon it, but it 4also serves the important purpose of preventing any water or acid which may accumulate on the top ot the cover sealing compound and destroying; the seal. By having,r this flange or ridge extending' upward from the surface of the cover arela tively deep trough may be provided Jfor the sealing compound without increasing the thickness or depth of the cover. lThis trough holds the sealing compound in place so that it can be neatly applied when sealing the jar, and when unsettling; the jar the compound will be held in position where it can again be used without waste.

ln order to readily unseal the jar and to repair leaks in the seal. l provide within the sealingr compound ind preferably to one side of thc center thereof-aud near the wa l ot the jar. a conductor 20 embedded in the compound and extending alonz the trough. with its ends 21 projecting out of the compound tor receiving terminal or connection pieces To these terminal pieces 22 are secured conductors 23 having connection pieces 2l adapted to tit the terminals from the plates` and in the preferred embodiment o't the invention l provide these connection pieces in the 'orm ot circular sp1-iupY clips` as shown in Fig; 3, so that they may be so far as myl compound in place' from leaking` under the soY snapped around any suitable portion of the terminal when it `is desired to connect up the conductor 20 with, the battery to melt the sealing compound, either for the purpose of unsealing the cover or to soften the compound in case of a leak so that it.' may be pressed in at that point to repair the same.

While Il have described in detail. the preferred embodiment of my invention, it is obvious to those skilled in the art that different changes in the construction and arrangement of the parts may be made without departing from my invention, and I do not vvish to be understood as limiting the invention other than as indicated inv the appended claims.

This isintended as a division of my copending application for improvements in storage batteries Serial No. 715,147 filed August 15, 1912.

aving thus described my invention, what I claim as new and desire to secure by Letters Patent, is

1. The combination of a storage battery jar having negative and positlve plates therein, terminals for the plates, a cover for the jar, a sealing compound extending around the edges of the cover and sealing the cover to the jar, a conductor embedded in the sealing compound, terminals to which the conductor is connected, conductors connected to said terminals, and connection pieces secured to said last conductors and adapted to fit the terminals of the plates, whereby the sealing compound may be softened by connecting the connection pieces to the battery terminals.

2. The combination jar having negative therein, terminals for the plates, a cover for the jar having a part near its edges forming, with the inner wall of the jar, a trough extending around the edges of the cover, a sealing compound in said trough for sealing the cover to the jar, a conductor embedded in said sealing compound, terminals to which the ends o1 the conductor are connected, and means for connecting said conductor terminals to the terminalsf of the plates for conveying current through said conductor to soften the said compound.

3. The combination of a storage battery jar, a cover for the jar having a portion near its edges which 'forms with the adjacent inner walls of the .jar a trough eX- tending around the cover, a sealing compound within the trough, and a strip of compressible material at the bottom of the trough below the sealing compound and eX- tending beyond the edges of the cover into engagement With the inner Walls of the jar to prevent the sealing compound, when hot, from getting down between the extreme of a storage battery and positive plates the jar.

4. The combination of a storage battery jar, a cover for the jar having a portion near its edges Which forms with the inner Walls of the jar a trough eXtendinv' around the cover, a sealing compound Within the trough, a strip of compressible material supported on the cover at the bottom of the trough below the sealingcompound and extending beyond the cover into engagement with the inner Walls of the jar to prevent the sealing compound, when hot, from getting down between the extreme edges of the cover and the adjacent walls of the jar, and means backing up said strip to hold it from lateral movement closely against the said walls of the jar.

5. The combination or a battery jar, a cover for the jar having a ridge projecting up from the top surface of the and eX- tending around the edges thereof to form with the inner wall of the jar and the outer edges of the cover a trough for receiving a sealing compound and projecting said compound from accumulated liquid on the cover of the jar, and said sealing compound'within said trough for sealing the cover on said jar.

6. The combination of a battery jar, a cover for the having a groove formed around its edges, a strip of flexible material within said groove and tightly fitting the inner walls 'of the jar, a ridge formed in the cover extending above said groove, and a sealing compound extending around the cover above the liexible strip and confined between said ridge and the inner walls of the jar.

7. The combination ol a storage battery jar, a cover for the Ijar having a ridge or flange extending ujnvardly from its surfaces near the extreme edges of the cover and extending around the cover to form with the adjacent inner surface ol the jar;and projecting portion of the cover between the inner surface ol the jar and said ridge a trough, a strip or' compressi blc material ovcrlapliing the edge ol' the cover and eX- tending around the same and into close engagement with the adjacent inner surface of the wallsof" the jar above the extreme edges ol the cover, and a scaling compound within the trough above Vsaid strip oil compressible material.
